This kinda crap is hardly limited to Detroit fans.
How about the NBA Laker riots in 2000 in Los Angeles? How about the 70,000 Vancouver, B.C. fans after they lost the Stanley Cup running thru the streets amidst clouds of tear gas? Or the Montreal fans in 93 after winning the Stanley Cup who did $10 million in damage and injured 50 police officers? How about the Univ of Wisconsin football fans who crushed 73 people after their football win against U of M? How about the local 8-year-old-and-under baseball league?
Of course, the kings of sports fan violence are the Europeans with their mass riots at soccer matches.
Bottom line: People have some real serious physcological problems when they take sports this seriously,
